There were a few threads in the Activanet forum about suppliers of de-catted exhaust pipes, to fit as a replacement for duff cats, especially as cats are a restriction on exhaust flow and therefore power output. It would not be difficult to make up a pipe as it is straight with just the swaged couplings at both or one end. You could even cut out the old cat and weld in a section of straight tube.
Only downside is at MOT time as it would be an instant failure not to have a cat fitted. However, I do have a cunning plan that I am fitting to my early MK1 Activa, which will remove the restriction of the catalyzer but still give me the correct emissions readings. Will let you know if it works. 8)
